I did some test on my deck when I first got it seeing the difference in load times when a game was installed on its m.2 SSD vs a Micro SD card and the difference was there but pretty negligible. a long load time that took 16 seconds on SSD took 18 on Micro SD. It isn’t something I’d personally notice unless I was timing it.

The thing with “easily serviceable” is that no matter the actual difficulty, once you need to involve a screwdriver to take apart a controller (anything other than a door you can easily open with your hands) you’ve lost like 85% of people. Most average people are not comfortable taking apart electronics to do ANYTHING and will just buy a new one and toss the old one in the trash when it stops holding a charge. But AA batteries? everyone is comfortable with replacing rechargeable AAs.

that’s honestly the best move, even if it is more expensive it’s totally worth it.

Hell, these corporations could even make more money selling you additional packs you could swap if you didn’t want to use rechargeable AAs. It needs to be the standard, it would keep so many controllers out of landfills when their batteries go bad. Microsoft kind of does this with the standard Xbox controllers, but in typical Microsoft fashion they make your first rechargeable pack a separate purchase. I’d still way rather have that than the built in batteries though.
